electricity for 10 cents (HyperIonPowerGeneration)
Hyperion's miniature nuclear modules could be easily transported and buried underground, with the ability to power up to 20,000 homes.
(PhysOrg.com) -- Underground nuclear power plants no bigger than a hot tub may soon provide electricity for communities around the world. Measuring about 1.5 meters across, the mini reactors can each power about 20,000 homes.
The small energy modules were originally designed by Otis "Pete" Peterson and other scientists at Los Alamos National Laboratory in
"Our goal is to generate electricity for 10 cents a watt anywhere in the world," said John Deal, CEO of Hyperion. "[The nuclear plants] will cost approximately $25 million each. For a community with 10,000 households, that is a very affordable $2,500 per home."
Because of their small size, the mini power plants can be assembled relatively quickly and transported by truck, rail or ship to remote locations, even places that currently do not have electricity. The power plants provide an alternative to current nuclear plants, which are large, expensive, and take about 10 years to build. Also, large-scale power plants don´t fit the needs of small populations or areas without available land. Hyperion´s modules can be connected together to provide energy for larger populations, as well.
In addition, the Hyperion modules have no moving parts to wear down, and never need to be opened on site. Even if opened, the small amount of enclosed fuel would immediately cool, alleviating safety concerns. "It is impossible for the module to go supercritical, ´melt down,´ or create any type of emergency situation," the company states on its Web site. Because the Hyperion plants would be buried underground and guarded by a security detail, the company explains that they´ll be out of sight and safe from illegitimate uses. Further, the material inside wouldn´t be appropriate for proliferation purposes.
"You would need nation-state resources in order to enrich our uranium," Deal said. "Temperature-wise it´s too hot to handle. It would be like stealing a barbecue with your bare hands."
The reactors need to be refueled about every seven to ten years. After five years of generating power, Hyperion says that the module produces a total waste of about the size of a softball, which could be a candidate for fuel recycling.
Hyperion now has more than 100 orders for its modules, mostly from the oil and electricity industries. The first order came from a Czech infrastructure company called TES, which specializes in water plants and power plants. TES ordered six modules and optioned another 12, with the first planned to be located in
Hyperion plans to build three manufacturing plants, with the goal of producing 4,000 mini nuclear modules between 2013 and 2023. Next year, the company will submit an application to build the modules to the Nuclear Regulatory Commission.
While acknowledging that the commercial development of mini nuclear plants is a lofty goal, Hyperion believes that the potential benefits of the technology make the effort well worthwhile. Along with bringing electricity to remote locations, the Hyperion modules could also be used to provide clean water for the 25% of the world´s population that currently does not have access to clean water. The modules can provide power to pump, clean, and process water, which in turn can help decrease disease, poverty, and social unrest.

Tips to protect your WiFi from hackers if you are using the BSNL/Airtel/Other Wireless Accesspoints
It could any one of us. Wake up one morning to discover that the Indian Mujahideen has hacked into our Internet account and sent out a chilling mail claiming responsibility for a terror attack on the nation.
The e-mails sent out in the aftermath of the Delhi and Ahmedabad blasts reveal that the Indian Mujhahideen hacked into unsecure WiFi networks to send out the terror e-mail.
While this trend may continue thanks to the number of IT professionals on the Students Islamic Movement of India/Indian Mujahideen rolls, it is up to us to ensure that we take utmost care while using the Internet.
Sameer Shekle, co-founder and COO, Aujas Networks, a digital security services provider, says Internet users could adopt the following methods to ensure that s/he is safe.
- Disabling the SSID broadcast. To some extent this makes it difficult for the hacker to detect the presence of a WiFi access point.
- Enable MAC address filter. Each network interface has a unique MAC address, by filtering it, one can to an extent control which machines can use the access point.
- Turn on WPA/WEP encryption. This ensures that traffic between a legitimate machine and an access point is not readable.
- Change default admin passwords for access points.
- Ensure access points are placed securely. In the centre of a room/office etc to minimise its signal strength outside the office.
Even after following the above precautions, your WiFI account could be compromised and hence, the things to look at are:
- Monitor usage of the access point. Have a clear inventory and knowledge about the position of each access point.
- Monitor the usage of the Internet link, to know what traffic is going out. For example, some corporate block e-mail providers like yahoo or hotmail. Hence, even if the access point is compromised, the hacker may not be able to use public e-mail systems.
- Consider a specific security policy for wireless networks. For example, most companies primarily use wired networks in the office as the primary media. Access points are used in common areas like conferences rooms etc. Hence, strict policies can be deployed on wireless networks as compared to wired networks.
Role of Digital Forensics:
Digital Forensics means the analysis of electronic media to detect forgery or manipulation. It is used to identify possible culprits and also to gather legal evidence to be used for prosecution.
Digital Forensics is a highly-specialised area and if not done using the right skills and tools could lead to evidence being deleted or not usable in the court of law. It is similar to that of criminal forensics and hence needs special skills and tools. Hence, it would be advisable for companies to understand their responsibility and the do's and don'ts during a breach.
Public e-mails systems have limited information about its users and normally provide it to law enforcement agencies on special request. This information is picked up during e-mail ID creation, usage etc.
Most usual information picked up is the source of the Internet Protocol, which can be masked using techniques like using others' WiFi networks. Hence, unless e-mail providers enable higher security mechanisms like special authentication while creating users not much can be done. It is not easy for e-mail providers to do this as, by definition, these e-mail systems are free and open for people to use.
